Gosund SP112
Flashing
The device can be flashed using tuya-convert. Fresh out of the factory it will be in autoconfig mode. When plugged in for the first time tuya-convert will pick it up directly.
If that doesn’t work out for you, disassembly and wired flashing is explained in this (German) video.
